Is HDA typically this poor?

[Blu_Ray_UK2007]

This is my inaugural electric vehicle, and I am acclimating to the distinctions from my previous Focus, which I cherished immensely.

One of the initial shortcomings I observed during the trip home after purchasing it was that while using the cruise control, the car exhibited a shake on the road. Initially, I believed the automobile was being affected by the wind, since I sensed it shifting beneath me and the steering wheel oscillating laterally. Upon braking and disengaging the cruise control, the shimmying ceased. After several excursions, I learnt that it occurred solely when HDA was operational. It appears to be perpetually overcompensating in an effort to maintain its lane position. Do they all engage in this behaviour?


A memorable experience with HDA occurred when navigating roadworks on the M3, with the cruise control set to 50, when the vehicle unexpectedly accelerated. I looked at the HUD and observed the speed limit indicator indicating 70, despite the absence of any road signs. During the return journey, the variable speed limit on the M25 indicated 50, although the system saw it as 80 and accelerated accordingly. What the heck!

The HDA deactivates each time cruise control is engaged unless I navigate the options to disable it permanently, if that is possible.

I can provide information regarding my Hyundai Tucson, which is equipped with the HDA capability, and my eldest son own a similarly equipped KIA EV6. HDA operates quite well on both vehicles.

I recommend that you schedule an appointment with your selling dealership and elucidate the issues encountered with the HDA engaged, as it should not function as you have described.


If you purchased the car as new, you have the option to reject it; the procedure is available online or through Citizens Advice.

Thank you for your response. It is a pre-owned vehicle. I am attempting to ascertain whether others have experienced these issues prior to contacting Kia, as I wish to save an unnecessary fee for diagnostics only to be informed that "they all do that."

My EV6 GTLS has reached 80 mph on the M25 several times in the same location. However, this occurs solely when the cruise control is adjusted to align with the speed limit, indicated by the green "NAV" on the dashboard.

I believe it is incorrectly interpreting a 60mph variable speed limit sign as 80mph. I believe maintaining the cleanliness of cameras is beneficial.


To avert this 'misdetection,' adjust the cruise control to little below 70, so eliminating the search for road signs. One must certainly heed alterations in speed limits, as this remains an integral aspect of driving.

Regarding your vehicle's "shimmy" with lane keep assist: I understand your perspective, but perhaps you should acclimatise to it. I perceive it distinctly via the steering wheel, albeit at a level I would classify as 'haptic feedback'; the vehic
le does not veer left or right but instead follows the contours of the lane gently.

This is not an HDA issue, as it merely maintains a fixed distance from the vehicle ahead. I propose that this is a Lane Keep Assist problem, maybe because to your unfamiliarity with it or because the camera may be obstructed by dirt. Last week, my Lane Keeping Assist (LKA) malfunctioned; during the outbound trip, it failed to maintain my position within the motorway lane as expected, only initiating corrective measures upon my approach to the lane marker. I was employing a relaxed grip to assess its performance, resulting in a noticeably more abrupt driving experience than usual. The return travel proceeded without incident, suggesting that either restarting the vehicle rectified the issue or a camera obstruction was resolved.
